How We Compared MFA Solutions<\/h2>\n
Every vendor on this list does the basics: a second factor after the password, a mobile app, an admin console. The differences that decide a purchase sit elsewhere, so each solution was checked against the same criteria:<\/p>\n
\n
Deployment.<\/strong> Cloud only, self-hosted on your own servers, or hybrid.<\/li>\n
Hardware tokens.<\/strong> Whether the vendor offers its own tokens, accepts third-party OATH tokens, or supports only security keys.<\/li>\n
Key integrations.<\/strong> VPN through RADIUS, Windows login and RDP, Microsoft 365, and on-premise directories.<\/li>\n
Pricing.<\/strong> Published starting price per user per month, free tier, minimums.<\/li>\n<\/ul>\n
Prices come from each vendor’s official pricing page. Where a vendor does not publish prices, the table says “Quote-based.” Features are taken from vendor product pages and documentation.<\/p>\n
